Answer: Liquid
Explanation:
Liquid and gases are fluids as they can flow. Convection takes place when the the particles having more energy is replaced with the particles having less energy.
The hotter particles moves and takes place of the colder particles when a liquid is heated. The liquid that lies in the hotter region is less dense than the colder regions. So, less dense particles move to replace the more dense particles.
Hence, the correct answer is Option B
The answer is the first option, "closing of the structures".
b. chemical digestion
c. peripheral digestion
d. mechanical digestion
Chemical digestion is the chemical breakdown of food
Good luck and hopefully this helped.
Answer: The correct answer is B. 6CO2 + 12H2O → C6H12O6 + 6H2O + 6O2
Photosynthesis is a process of synthesis of food in green plants and algae. In this process, energy from sunlight is absorbed by chlorophyll pigment in the presence of CO₂ and H₂O and it is used for the formation of food, which is a carbohydrate ( glucose).
Thus, CO₂ and H₂O are used as reactants and glucose ( C₆H₁₂O₆) is synthesized as a final product of the process along with O₂ ( oxygen).
Option B) is the correct balanced equation for this process.
Answer:
B. 6CO2 + 12H2O → C6H12O6 + 6H2O + 6O2
Answer: The correct answer for the blank is-
Pulmonary artery.
Right ventricles receive deoxygented blood ( from right atrium) when tricuspid valves ( present between right atrium and right ventricle) open.
When ventricles contract, this blood flows from right ventricles to pulmonary artery, which takes it to the lungs.
In other words, the deoxygenated blood ( carbon dioxide containing blood) is sent to lungs via pulmonary artery so that it is exchanged with the oxygenated blood at lungs, which is then sent to the heart for its circulation in the entire body.
